Cardiac catheterization involves passing a thin flexible tube (catheter) into the right or left side of the heart. The catheter is most often inserted from the groin or the arm. This article discusses how to care for yourself when you leave the hospital.
When You're in the Hospital
A catheter was inserted into an artery in your groin or arm. Then it was carefully guided up to your heart. Once it reached your heart, the catheter was placed into the arteries that deliver blood to your heart. Then contrast dye was injected. The dye allowed your doctor to see any areas in your coronary arteries that were blocked or narrowed.
If you had a blockage, you may have had angioplasty and a stent placed in your heart during the procedure.
